Research ArticleOpen accessIn the keywordsOn the Sensitivity of a Dynamic Measure of Financial InequalityGuglielmo D’Amico, Stefania Scocchera, Loriano StorchiIn the present work, we investigate the sensitivity of the dynamic Theil index computed under a Markov reward model with respect to structured perturbations affecting the underlying Markov process. The model is applied to the sovereign credit spread evolution as a proxy for financial risk, which are driven by the sovereign credit rating dynamic. The introduction of such perturbations allows … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 25 Oct 2019 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Environmental Risk on the Financial Structure of Oil and Gas ProjectsBagilya Karsybayeva, Alberto De MarcoThe risk profile of a Build-Operate-Transfer (BOT) project affects its debt service ability. In particular, the total risk profile of an oil and gas project is heavily influenced by its environmental risk exposure. However, this risk is often not given a considerable weight in risk analysis, resulting in underestimation of project’s total riskiness and consequent overestimation of the debt capacity. … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 22 Jan 2013 · 7,195 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact of Information Asymmetry on Municipal Bond Yields: An Empirical AnalysisKenneth Daniels, Demissew Diro EjaraProblem statement: There is a significant difference between the interest rates on the GO and the RV municipal bonds. We sought explanation for this difference in differences in information asymmetry between the two types of municipal bonds. GO bonds finance general municipality expenditures and repayment is from general tax revenues. RV bonds finance special projects and repayment is from cash … …American Journal of Economics and Business Administration, Vol. 1, Issue 1 · 31 Mar 2009 · 8,033 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCritical Aging Segments of Power Transmission LineH. H. Goh, N. E. Chin, Q. S. Chua et al.Nowadays, blackouts or sags of a conductor are threatening the safety and stable run of the power transmission lines. These phenomena happen due to the environmental conditions which change over the time, such as aging or temperature variations, precipitation and hotspots of power transmission lines as a result of extreme weather conditions. A precipitation condition result loses of heat from … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 9 Dec 2013 · 9,264 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Virtual Repository Approach to Departmental Information SharingZulikha Jamaludin, Wan Hussain Wan IshakProblem Statement: Realizing the difficulties in information sharing among the academicians, this study introduces an alternative information sharing model supporting information management features. Objective: The model is designed in an attempt to facilitate information distribution and information sharing at minimum effort and cost.

Research ArticleOpen accessIn the abstractHybrid Enhanced Neighbourhood and Latent Factor Model for Cold-Start RecommendationsAmritha P, Rajkumar KKAmong different recommendation strategies, collaborative filtering remains a commonly utilized method for generating personalized suggestions. The traditional collaborative algorithms face performance declines due to the sparse rating of data and the item cold-start problem. To overcome these challenges, this paper introduces a novel hybrid model called HCE-KNNCF (Hybrid Cognition-Enabled K-Nearest Neighbor Collaborative Filtering). The proposed model generates predicted rating by … …Journal of Computer Science, Vol. 22, Issue 9 · 21 Sep 2026 · 622 accessesView PDFCite
